COMPOUND SAFE OR, VAULT DOOR.

To all whom it may concern:

Be it known that I, SAMUEL W. Fisrr, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Compound Safe or Vault Doors, of which the following is a specification.

The present improven'ient relates to safes or vaults, and more particularly to the doors thereof, the object of the invention being to provide an improved double or compound door comprising a plurality of doors each a complete door in itself and each having means for securing it within the jamb of the safe or vault body, but which doors are very rigidly connected together in an improved manner so that the separation of one door from another will not only require the rupturing of the holding means between the doors, but also of the locking means of. the outer door in the safe or vault body, the present invention being an improvement in part upon those shown and described in my 492,869, filed rrpril 29, 1909, and Serial No. 526,486, filed Nov. 6, 1909. In the first of said improvements the doors were secured together by means of locking lugs interlocked by the rotation of one door relatively to the other, and in the last of said improvements the doors were secured together by sliding one door on to the other and bolting them together. In the present improvei'nent, however, one door is secured on another by rotating it into position, to permit which opposed portions of each door are provided with screw-threads.

()ne of the advantages of a compound door made up of separate but rigidly connected doors is that a different form of spindle from the tapered spindle heretofore deemed essential. may be used. In other words, in safes as heretofore constructed,

when a spindle was used projecting inwardly from the front face of the door it was deemed necessary to taper this spindle to prevent it from being pushed inward, and to also in some way provide means for preventing it from being pulled outward. But the tapered formation of the spindle was in some respects a disadvantage. In the present improvement, however, by forming the doors in the manner set forth they may be spaced apart to form a chamber therebe- Specification of Letters Patent.

tween and thus enable a straight spindle to be used and to be inserted from the inside of the outer door before this door is placed in position, and to therefore be provided with an enlarged head which will prevent any possibility of the spindle being drawn through the door from the outer side thercof. The spindle may also be of such construction that it may engage the front face of the inner door, so that any possibility of forcing it inwardly is avoided.

In the drawings accompanying and forming part of this specification, Figure l is a rear view of this improved door; Fig. 2 is a cross-sectional view taken in line 22, Fig. 1; Fig. 3 is a cross-sectional view of the outer door; and Fig. 4. is a cross-sectional view of the inner door.

Similar characters of reference indicate corresponding parts throughout the figures of the drawings.

This improved compound door comprises two doors, an inner door A and an outer door B. The inner door comprises a body 2 preferably having a rearwardly extending flange 3 provided with the usual locking lugs at and bolt openings 5 for the reception of suitable bolts for securing the door against rotation, the locking lugs preventing the withdrawal of the door after its rotation into position in the usual manner. This inner door is also provided with a forwardly extending boss 6 having a recessed or chambered front portion 7. This boss or annular member is of less diameter than the inner door body, and is provided with threads around its periphery and also with openings 12 for the reception of the bolts. This annular member or boss 6 thus forms an annular space for the reception of the flange of the front or outer door here inafter referred to. The space is of such size as to permit the tapered joint surfaces of the inner and outer doors to be continuous, in a manner which will be readily understood. The front or outer door 13 also comprises a flanged door having suitable lugs 8 adapted to cooperate with similarly formed lugs carried by the body jamb, so that both doors, when in the jamb, are each separately locked therein by these locking lugs. The inner flange 10 of the outer door fits on to the boss or annular member 6 of the inner door and is provided with interiorly located threads 11 adapted to mesh with the threads of the annular member or boss 6 of the inner door, whereby the doors are interlocked together by rotating one on to the other. F or rigidly securing the doors in this position they are keyed together by a key 13 which extends through the flange of the outer door and into the boss and body of the inner door, a suitable key-way 14 being provided for this purpose. The bolts which are located in the bolt openings 12 of the opposed flange and boss will also prevent the rotation of one door relatively to the other. In this manner the two doors are very rigidly locked together for rotation as a single structure within the jamb when made in the form of a rotary door.

When it is desired to use a spindle for any purpose, the outer door is provided with an opening 15 extending through the body portion ,16 thereof for the reception of a straight spindle 17 provided with an enlarged head 18 and with an inner end portion 19 adapted to engage the front face 20 of the body of the inner door. This spindle may be inserted into position from the inside of the front door before the two doors are secured together, and consequently enables the provision of a spindle with an enlarged head which will positively prevent the withdrawal of the spindle outwardly and also enables the provision of a spindle which may have its inner end engaging the front face of the inner door, and thus prevent the forcing of the spindle inwardly, thereby doing away with the use of a tapered spindle.

This compound door, itwill be observed, is made up of a pair of doors each of an integral structure, rigidly secured together and each having its separate locking means for locking the door within the jamb of the safe body, the doors being so formed that they are spaced apart to form a chamber between the rear of the outer door and the front of the inner door.

In practice the bolts which secure the two doors against rotation may also be utilized to project into the amb to lock the door in the jamb against rotation, and for this purpose they would, of course, be connected with a suitable automatic or bolt operating means such as is usually provided for that purpose, and which would be located within the chamber formed between the two doors, these bolts in their normal unlocking position projecting through the openings provided in the forwardly extending flange of the rear door and the rearwardly extending flange of the front door.

By constructing the doors in the manner set forth the spindle may be provided with an integral head, thus obviating the necessity of providing any threads or other holdstripping the threads and thereby releasing the head from the spindle. In the construction shown this spindle will control the bolt operating means located in the chamber between the bodies of the doors when this form of bolt controlling means is used.
